COFFEE SUBSTITUTE.

To all whom it may concern:

Be it known that I, JOHN H. KELLoco, a citizen of the United States, residing at the city of Battle Creek, county of Calhoun,and State of Michigan, have invented certain newand useful Improvements in Cereal Coffee or Coffee Substitutes, of which the following is a specification.

This invention relates to improvements in cereal coffee or coffee substitutes.

The object of this invention is to provide a cereal cofiee which is easily prepared and one by which the beverage is prepared for immediate use merely by adding hot water to the preparation.

In carrying out my invention, I prefer to employ a cereal coffee produced by combining malted cereals such as malted wheat, barley, or rye, and barley sprouts, with bran and unmalted wheat, rye, and barley, and roast the whole together. The proportions are preferably about as follows: To a mixture containing about equal parts of bran, wheat, rye, and barley, I add from five to ten per cent. of'malt and preferably a percentage of barley sprouts. The malt is added for the purpose of liquefying the starch more completely. It also afi'ectsto some extent the flavor. The barley sprouts are added mainly on account of the effect on the flavor. A single grain may be used with quite satisfactory results, that is, either wheat, barley, or rye may be combined with about ten per cent. malt, but I preferably use the combination of the cereals stated. The barley'is added to about one-third of the cereals (wheat, rye, barley or other grain) with water after first cooking the grain, then digested until the starch is liquefied. The balance of the ingredients are then added.

The mixture is thoroughly roasted or baked. This roastedv mixture is boiled to extract the soluble matter, the boiling being carried on for from half an hour to an hour, according to conditions. It is desirable to boil for a considerable period until substantially all the soluble matter has been extracted. The liquor is then extracted from the insoluble matter and concentrated or evaporated to a syrup like consistency.

The insoluble matter from which the extract is made, is dried and about one-half of this residue, more or less, is mixed with the concentrated extract or syrup and dried and coarsely ground, the object of the grinding being to break up the material which may have adhered together in more or less of a mass unless great care has been taken in the drying. The extract is thoroughly mixed With the granular residue so that the sur faces of the insoluble granular material are coated with the extract in soluble form and isready for solution anddissolves at once when brought into contact with boiling water. Sugar may be added to the extract if deslred in such quantities that the final product is suitable for use without the addition of more sugar. Sweetened cofl ee is, however, objectionable to some and the product is satisfactory without theaddition of the sugar and the sugar may be added at the time of serving as in ordinary coffee if desired.

Instead of using the dried grounds or extract may be combined with a quantity of the material such as is used in preparing the extract or other granulated material. In stead of the particular ingredients I describe for preparation of the extract, cereal cofiee of the character now on the market may be used with quite satisfactory results. i For instance, the product known on the market as Caramel cereal may be used, this being boiled to extract the soluble matter and otherwise treated as above stated.

' The generic idea of coating any suitable material with cereal coffee liquor is not claimed herein but forms the subject matter of my co-pe-nding application, Serial No. 698,586, filed May 20, 1912.

The condensed or evaporated extract or liquor being on the surface of the granules is very quickly and thoroughly dissolved merely by the addition of hot water so that the beverage is very easily prepared from the product. The product vmay be used without drying, but 1n order to be kept successfully and without preparation, it should be thoroughly dried when it may be'kept for a long period, without material loss of strength and has the granular appearance of cofi'ee.

The condensing or evaporation of the liquor drives off certain volatile acids which are produced by the roasting step so that the final beverage or product is superior, in my opinion, by being largely freed from these objectionable acids, to the beverage preresidue from which the extract is made, thecoffee consisting of boiling cereal coffee, ex-

pared by the boiling of a quantity of the socalled cereal coffee and is superior to the extractor decoction made by boiling the roasted mixture described previous to its being concentrated.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The process of manufacturing cereal coffee consisting in boiling cereal coffee, extracting the liquor thus obtained, and mixing cereal coffee with the extract to form a coating thereof upon the surfaces of the cereal coffee. I

2. The process of manufacturing cereal coffee consisting in boiling cereal coffee, eX tracting the liquor and concentrating the, same, and mixing coffee to form a coating on thereof.

3. The process of manufacturing cereal coffee consisting in boiling cereal colfee, extracting the liquor and concentrating the same, mixing the extract with cereal coffee to form a coating on the surfaces thereof, and drying.

4. The process of manufacturing cereal coffee consisting of boiling cereal coffee, extracting the liquor and evaporating it to a syrup-like consistency, combining sugar therewith, and mixing cereal colfee with the extract to form a coating on the surface thereof.

5. The

the surfaces process of manufacturing cereal tracting the liquor and evaporating it to a syrup-like consistency, and mixing cereal coffee with the extract to form a coating upon the surface'thereof.

6. The process of manufacturing cereal coffee consisting in boiling cereal coffee, extracting the liquor and evaporating it to a syrup like consistency, mixing cereal coifee with the extract to form a coating on the surface thereof, and drying;

7. The process of preparing cereal coffee consisting of boiling cereal coffee, extracting the liquor and evaporating it to a syrup-like consistency, combining sugar therewith and mixing cereal coffee in granular form with the syrup to coat the surface of the granules with the syrup. 7

8. The process of preparing cereal cotfee consisting of boiling cereal cofiee, extracting the liquor and evaporating it to a syrup-like consistency, and mixing cereal coffee in granular form with the extract to coat the surfaces of the granules with the extract.

9. The process of preparing cereal cofiee consisting of boiling cereal coffee, extracting the extract with cereal the liquor and evaporating it to a syrup-like consistency, mixing cereal coffee in granular form with the extract to coat the surfaces of the granules with the extract, and drying.

10. A cofiee substitute consisting of cereal colfee coated with a syrup consisting of evaporated cereal coffee liquor and sugar.

11. A coflee substitute consisting of cereal cofiee coated with an extract consisting of evaporated cereal cofiee liquor.

12. A. coffee substitute consisting of cereal cofiee in granular form, the granules of which are coated with a syrup consisting of evaporated cereal coffee liquor and sugar.

13. A coffee substitute consisting of cereal coffee in granular form, the granules of which are coated with a syrup consisting of evaporated cereal coffee liquor.

In witness whereof, I have hereunto set my hand and seal in the presence oftwo witnesses.
